  • Patent number: 5805780
    Abstract: A photographing box is arranged to reduce a time taken from photographing an object to printing the image of the object. The photographing box is intended to be manufactured at low cost and more easily maintained. The photographing box includes a photographing mechanism house for housing a photographing mechanism and a photographing space section. If paid, the photographing device is operated to illuminate an object, photograph the object, and do some image processing like image magnification or reduction or image layout. Plural images sized for different uses output on one cut sheet by a sublimation transfer printer. The photographing box operates to print out the image at high speed and is manufactured at low cost and more easily maintained.

  • Patent number: 5795527
    Abstract: A decorative transfer material includes a base film, a decorative metal vapor deposition layer, a metallic reinforcing layer covering the whole rear face of the metal vapor deposition layer to thereby reinforce the metal vapor deposition layer, a retainer layer for securing the metallic reinforcing layer to the base film, and an adhesive layer for bonding the metallic reinforcing layer to a to-be-decorated object molded by resin. The metallic reinforcing layer is formed of a metallic powder resin layer or a metallic foil layer. After the transfer material is set in dies for injection molding, the dies are closed. Simultaneously with formation of synthetic resin injected into the in-mold dies, the resin is bonded with the metallic reinforcing layer of the transfer material by the adhesive layer. Thereafter, the in-mold dies are opened and the base film of the transfer material is removed, whereby a decorated article is obtained.

  • Patent number: 5774164
    Abstract: The present invention aims to provide a thermal transfer image-receiving sheet which does not suffer from any cockle problem, during printing, associated with a printer or a dye transfer film used. The thermal transfer image-receiving sheet comprises a substrate sheet and, provided on at least one surface thereof in the following order, an intermediate layer and a receptive layer, the intermediate layer containing either an acrylic polyol or cellulose acetate butyrate.Further, the present invention provides a thermal transfer image-receiving sheet which has a capability of preventing curling and causes no damage to an image-receiving surface even when image-receiving sheets put on top of each other or one another are used. This thermal transfer image-receiving sheet comprises a back surface layer provided on a substrate sheet in its surface where no image is to be formed, the back surface layer containing an acrylic polyol.

  • Patent number: 5453775
    Abstract: A medical image forming method including, the steps of superposing a three-primary-color thermal transfer sheet and an image receiving sheet, the thermal transfer sheet having a base film and three color dye layers of yellow, magenta, and cyan, each of the dye layer; being composed of a dye and a binder, the image receiving sheet having a dye accepting layer heating the rear surface of the thermal transfer sheet with a heating device in an image shape; and driving and controlling the heating device with a control unit so as to form a full color image on the image receiving sheet. The control unit is adapted to compensate tones of the image so that chromaticity values thereof formed on the image receiving sheet are in a region defined by four points of (a*=0, b*=0), (a*=20, b*=-5), (a*=18, b*=15), and (a*=0, b*=15) when an achromatic color signal is input and L*=80.

  • Patent number: 5045487
    Abstract: A thin film transistor including a glass substrate and a gate electrode which is formed on the glass substrate. Source and drain electrodes are also provided. An insulating film covers at least the gate electrode and an amorphous semiconductor layer is formed on the insulating film. The semicondcutor layer includes a first portion having the source electrode formed thereon, a second portion having the drain electrode formed thereon, and a third portion formed between the first and second portions and located above the gate electrode, having a thin thickness which allows photolithographic light to permeate therethrough.

  • Patent number: 4818981
    Abstract: An active matrix display device of an improved and simplified configuration and a driving method for the same are disclosed. The display device according to the present invention is characterized in that data bus lines and scan bus lines are separately formed on first and second transparent substrates respectively and the drain electrode of each TFT on the second substrate is connected to the scan bus line to be addressed next. This configuration eliminates earth bus lines of the prior art. This arrangement has effects of simplifying a bus line design and obtaining a higher yield and an increased opening rate for each display element. In order to drive the above device, an address pulse having a stepped waveform is used. Each address pulse has Vgon, Vgc, and Vgoff levels, and a width of two horizontal scan time.
